The technology will need to be introduced slowly to instill confidence for the average driver. The tech will need to prevent a few accidents that the drivers realize would not have been avoided otherwise. This will only happen with a driver assist system much like anti-lock brakes, not with a totally automated system because every collision or minor bump with an automated system will be big news and one more example that will allow people to say "this won't work."
Even if the system works perfectly it doesn't mean that the public will embrace it unless there is confidence and motivation to do so.
